At Interpack 2026, packaging technology specialist Sidel has unveiled a next-generation edible oil bottle that signals a shift in how PET packaging is designed and manufactured.

The 1L bottle, produced using advanced laser heating technology, introduces a redesigned structure that reduces weight by 20% compared to conventional halogen-blown alternatives, without compromising performance across consumer use or supply chain demands.

Weighing just 16.5g, the new bottle achieves a 4g reduction versus a comparable 20.5g halogen-blown version. The innovation lies in how material is distributed: PET is concentrated only in areas that contribute to mechanical strength, while excess material is eliminated elsewhere.

This targeted approach represents a departure from traditional packaging design, where additional material has often been used as a default method to ensure strength.

At the centre of the design is Sidel’s Power Ring, which reinforces key stress zones to maintain durability during opening and pouring. The structure also preserves grip for consumers, an essential consideration in edible oil packaging.

From a logistics perspective, the bottle maintains vertical strength and top-load resistance comparable to heavier formats, ensuring it can withstand transportation and storage conditions across the supply chain.

The bottle is manufactured from 100% recycled PET (rPET), aligning with growing industry demand for sustainable packaging solutions. By combining recycled materials with reduced plastic usage, the design supports both circularity and material efficiency goals.

At Interpack, Sidel is showcasing the laser-blown bottle alongside its halogen-blown counterpart, giving industry stakeholders the opportunity to directly compare weight, strength and performance characteristics through interactive displays.
